As for the closing structure of the flat belt 23 with respect to the supply / discharge opening 37 of each case 11, the partition plate 35 corresponds to the bottom plate 15 of the first embodiment, and the description of the structure is the same as that of the first embodiment. .

(Regarding the conveyed material loading portion C at the conveyed material supply position P) The lower end of the second wrapping transmission B is bent below the lower end of the first wrapping transmission A and protrudes horizontally.
On the flat belt 23 at the lower end of the second wrapping transmission B, both partition plates 38 for carrying in are mounted. The goods carried between the two partition plates 38 and placed on the flat belt 23 are:
While being held between the accommodation room 36 of each case 11 and the flat belt 23, the material is transported from the load supply position P to the load discharge position Q. The transported material unloading section D at the transported material discharging position Q
Then, the flat belt 23 gradually moves away from the supply / discharge opening 37 of each case 11, and the conveyed article is discharged on the flat belt 23.

The second embodiment has the following feature (a) (other than the other technical ideas described later). (A) The closed end portion 27 where the supply / drain opening 37 of each case 11 of the case endless continuous belt 10 and the flat belt 23 come into contact with each other, in a direction orthogonal to a plane including the extending direction R of both chains 7 . Bisection on both sides
And at the middle part which is the boundary between the two winding transmissions
The movement restricting portion 30 is provided so as to incline so that the distance L to the link 7 is maximized . Therefore, it is possible to prevent the flat belt 23 from swaying with respect to the supply / discharge opening 37 of each case 11 in the closing portion 27. Therefore, the transported goods carried into the accommodation room 36 of each case 11 are transferred to each case 1.
1 and the flat belt 23 can be securely held and carried. This point is the same as the feature (b) of the first embodiment.
